Oregon Power Mate Rim Sprocket System 3/8" -7 Tooth, 7/8" Spline Bore

The Power Mate® Rim Sprocket System from Oregon is the most effective way to drive saw chain on most chain saws. The system includes a clutch cup with spline and a replaceable rim sprocket which floats freely on the spline, maximizing the saw chain–bar groove alignment. The rim is designed to be replaced, maximizing operational life and reducing overall operational costs.

Also available through the drop-down menu is an optional replacement sprocket washer.
